UNiTso STATES PATENT oFFIcE OIL WELL APPARATUS Willis Wilson Bryant, Chatsworth, Calif.

Application December 17, 19,31 Serial No. 581,631

The present invention relates to oil paratus; and its object is to provide an Claims.

well apimproved apparatus of that character whereby the oil-delivering pipe or tubing may be raised o without plugging r lowered the same or suspending or interfering with the flow of oil therethrough in the regular manner; and more particularly, to provide in such apparatus,

thus raising or lowering the cil-pipe ing; such pipe or tubing in having the usual oildischarging head or Christmas tree, means for or tuband further, to provide means for holding desired raised or lowered position; and further, to provide such apparatus and holding means with a downwar d tubular extension through which said pipe or tubing cxtends, provided with a dam or packing preventing gas from passing upwardly into the oil,

' etc.;

and further, to provide such pipe or tub- Aing with an upwardly extending rod having detachable sections for raising the pipe or tubing.

These and any other or more specic objects hereinafter appearing are attained by,

and the invention finds preferable embodiment in, the structure and devices particularly described in the body of this specification and illus trated by the accompanying drawing forming part thereof,

in which:

Figure 1 is an elevational view, pa

rtially in axial section, of an oil well pipe with dischargecontrolling means and an embodiment vention applied thereto;

of my in- Figure 2 is a transverse sectional view thereof taken'on line 2-2 of Figure 1; and

Figure 3 is an elevational view (enlarged) of the upper portion of said pipe with its ,strainer section and lifting rod extension secured thereto. In the drawing is illustrated apparatus for oil wells and the like, comprising a pipe designated generally 1 passes from vents or branching discharge pipes 2, trolled by suitable valves having the hand wheels 5, 6, '7 respectively. tubular support 8 contains this pipe 1 or tubing through which the oil the well and is discharged through 3, 4 conoperating An upright and has at its top a radial ange 9 carrying on its upper side a device for holding said pipe in desired vertical position (as hereinafter explained), the circular bottom plate 10 of the casing 11 of said device being secured to ange 9 by bolts 12 passing through these parts, suitable packing rings 13 being interposed therebetween.

The discharge head or ignated generally 14 (comprising the Christmas tree desdischarge pipes 2, 3, 4 and their controlling valves) is mounted on the upper side 15 of casi ng 11b? hollow threadedly-connected members or sections-the circular ring 16 secured asby bolts 17 to said upper end, the section 18 and the diametrically enlarged section 19 to which the lower hollow end 20 of the discharge head 14 60 is threadedly-connected at 21. The oil-carrying pipe 1 extends upwardly through the casing 11 and said sections 16, 18 and 19, spacedly therefrom, the oil being discharged from this pipe through the vents or holes 51 of the strainer 65 section 22 and passing thence through the discharge head 14 and its valve-controlled branches.

I provide a rod extension for the oil pipe 1 comprising a required number of threadedlyconnected sections 23, the lower one being connected to the pipes strainer section 22 by a threaded collar 24, said rod extension passing upwardly through the vertical branch 2 of the discharge head 14.

Said branch is provided with a hollow exten- 75 sion 25 connected thereto by a threaded collar 26 and containing a packing or gland 27 with a compressing plate 29 secured in `place by a threaded cap 28, carrying on its upper side a conical collar 30 seating in a corresponding depres- 3 sion in a collar 31 on the upper side of the cap 28. Suitable means for engaging the oil pipes rod extension 23 for raising this pipe to desired position, are provided, so that the oil pipe may be adjusted to the vertical position and at the depth at which the oil will flow therethrough in the desired manner and to the best advantage.

Such means, as shown, is the top member 32 threaded into the uppermost section 23 of the rod extension. Suitable lifting tackle (not shown) may be connected to this top member.

I provide suitable means for holding the oil pipe or tubing 1 in the vertical position to which it has been thus raised. In the particular form of such holding means illustrated in Figures 1 and 2, slid- 95 able clamp members 33 holdingly engage the pipe 1 on its opposite sides, having concave inner surfaces 34 contacting said sides. These members 33 are slid into and outl of pipe-holding position by screws 35 whose heads 36 turnably engage 100 between pins 37 on said members and which are threaded in the arms 38 of the casing 11 and pass through the plates 39, having compressible members 40 at their inner sides. The shoulder 4l of the pipes strainer section 22, or threaded collars connecting pipe sections, may be brought to rest- .ing position on the upper sides of the clamp members 33 thus positively holding the pipe 1 in elevated position, the openings 42, 43 through the horizontal sides of the casing 11 being large member 44 closing the space vand preventing gas from passing up through said passing of said shoulders,

member 44 and through the opening 43, `in the bottom plate 10 of the casing 11, etc. and thus into the stream of oil discharged through -the ber 45 sliding down with .whereupon it may losses, dangers and The apparatus is operated as follows to raise or lower the oil pipe 1 to a desired depth in the well Vand without suspending or interfering with the regular ilow of oil through the discharge head or Christmas tree 14. The shoulder 41 of the oil pipes strainer section 22 being in resting positionon the clampimembers 33 and the member 25 (which contains the gland 27) having been screwed on the top of the discharge head 14,Y the oil pipe extension rod (i. e. a suilicient number of its threadedly-connected sections 23) is pushed down inside the vertical arm 2 of the head 14 and the gland 27 and screwed into the strainer section 22 or its top collar 24 (as shown in Figure 3) the lifting tackle (not shown) being applied to the top member 32 of the extension rod and the clamp members 33 released from the pipe 1 and shoulder 41, the tackle is operated to lower the pipe 1 to the desired depth in the well, the packing memthe pipe to prevent gas risingv above it4 as hereinbefore explained, etc. The strainer section 22 now lowered into the tubular member 44 functions as it does in the section into the space 50 between the pipe 1 and surrounding tubular member 44 and above the member 45, and through the openings 43, 42Y

through the casing 11 and through the discharge head 14. i,

VBy thus raising and lowering the pipe 1 (with its strainer section through which oil passes therefrom) to tical position for the oil pipe may be ascertained; be clamped at some point in ts length or inthe length of its rod extension in that ascertained best position.

The extension rod being marked to'V indicate said position, the pipe 1 may be permanently secured therein by' suitable supporting means. The process oflowering and raising the oil pipe to thus ascertain the depth at which oil will ow therethrough to the best advantage (with the tendency to change the oil and gas ratio) is thus carried on without removing the discharge head 14 or plugging the oil pipe with the attendant inconvenienceand without suspending or interfering with the ow of oil from the discharge head in the regular manner. The strainer section 22 may be drawn out of the section 19 for cleaning the same, etc.

Means are provided 4for preventing the upper sections of the oil pipe or of its extension rod against unscrewing from lower sections (thus leaving such lower sections in the structure), such as providing looser or coarser or more readily released threaded-connections between lower sections than between the upper ones.

The invention being intended to be pointed out in the claims, is not to be limited'to or by de- VYvent and a discharge vent section 19, -the oil passing out ofthe strainer different.: positions, the best ver-I tails of construction of the particular embodiment thereof illustrated by the drawing or hereinbefore described.
